• Access 2010 tricks: Ghost Tables

  I'm working on upgrading a client of CF5 CF10 as 2010 access to SQL Server Express 2012.

  I suspect that they recently moved from Access 2000 to 2010 on some message that I fell due. Don't know if it's German for this conversation or not, so I thought I'd throw that in.

  In the new environment CF10, I had a request fails. At first glance, it appeared that one table has not met during the conversion.

  Check my backup copy of the Access database - this table is not there.

  Tested production (CF5 running Access) system and this program works.

  Looked in the production Access database - and the picture is NOT there, either!

  What is this magic?  I do not see the stored procedures, and it is not a slider (CF5 do not have this ability).

  This is the query:

  < cfquery name = "get_job" datasource = "m" >

  SELECT *.

  OF validate_jobnumber

  < / cfquery >

  How is it possible to query an Access table that does not exist?  Where should I look for this mythical creature?

  RLS

  Too bad, think about it.  The copy I had do not have applications in it. There are a number of queries in the Access database. RLS

• How do you return a blank in table 2, when there is no data in the cell related in table 1?

  I run a recreational League of golf and have been recording the scores of the players (50 + players in total) with the intention of maintaining a form of disability from the League.

  So far, I did most of the calculations manually in number. Recently, I have experimented using the Lookup function but have encountered a problem with the time where the player does not play this week.

  In table 1, where I do all scores record cel when they do not play is left blank. However, in table 2 than corresponding cel returns a 0... strikes completely out of whack handicaps.

  Here is what I used in table 2 for the information of table 1...  SEARCH (name, 2016 Stats::Table 1 $Last: $ name, 2016 Stats::Table 1::G44)

  I also tried to add an IF statement, but I have obviously not understood correctly as he said I tried to refer to a cel in the statement itself.

  Example of the disability Page in the table 2 list a 0 is returned in cel 6... which is then averaged in the cel of last second... namely the problem. The cel with the 6 in it is a formula that counts the number of moves played and see it 6 because it counts as a trick played 0. This shows the wrong average score of 65.666

  Them	A	78																						1	78
  Me	Me	80	75	81	0	81	77																	6	65.6666666666667	-10

  As it appears in table 1. indicating the total number of rounds played in 5 and returning the precise average score of 78.8

  Hi pondball,

  (Could be my 'golf name' somedays)

  

  Formula in Handicap::B2 and filled to the bottom and right at Handicap::X4

  = IF (LOOKUP ($A, data: $A, Data::B)=0,"",LOOKUP($A,Data::$A,Data::B))))

  IF compared the results of the first SEARCH and if it is zero, returns an empty string. If the comparison returns FALSE, the second SEARCH is called, find and returns the result of zero. AVERAGE does not take into account all results of text, including the string NULL, a zero-length text value.

  COUNT (used in the column count the number of turns) also ignores the text values.

  4th place of disability shows one of the reasons for not using LOOKUP.

  SEARCH alwas accepts a "close fit" with the search value. 'near match' for RESEARCH is defined as 'the largest value equal or less than the value of the research', and for the values text, "less than or equal" can be described as "identical or come forward in a list of items of text in alphabetical order.»

  For us, the other two values in the name list are 'less' us and the most important is 'Them', the values for 'Them' are returned.

  For this reason, I tend to use VLOOKUP instead of RESEARCH in many cases.

  VLOOKUP present the disadvantage of requiring her research-where location which will be the first column of the lookup table (which is not a problem here, because the location of the research is one ot the column data table).

  But also has the advantage of af being able to require an "exact match" search value.

  Here's the same tables of two, with VLOOKUP replacing LOOKUP. Note that the VLOOKUP function has a different syntax than the LOOKUP function.

  

  Formula VLOOKUP in Handicap::B2, filled with verse down and right at Handicap::X4:

  = IF (VLOOKUP ($A, Data: $A:$ X, COLUMN (), FALSE) = 0,"", VLOOKUP ($A, Data: $A:$ X, COLUMN (), FALSE) ")

  Written as above, the formula works correctly in rows 2 and 3, but will just return the error in the 4th row triangles, since it will not find a match (exact n) for 'Us' in column A of data.

  After confirming that it produces no unexpected error, wrap the formula in function SIERREUR as shown below and repeat the filling down and the right filling operations above.

  SIERREUR function interrupt all errors, including those affecting the results without your knowledge if they occur. Always delay adding IFERROR until you know what are the errors he fools.

  =IFERROR (IF (VLOOKUP ($A, data: $A:$ X, COLUMN (), FALSE) = 0,' ", VLOOKUP ($A, data: $A:$ X, COLUMN (), F ALSE))," ")

  Y2: = COUNT (C2:X 2)

  Z2: = AVERAGE(C2:X2) (base form)

  Z2: = IF (Y = 0,' ", AVERAGE (C2:X 2)) (real form)

  The encapsulation of the AVERAGE function in the IF statement deletes the calculation if the number of items to the average value is zero, AVERAGE preventing from return to a division by zero error. The number of circles in the column there is NOT used in the calculation of the average (AVERAGE did his own count), but is used as a switch 'OK to calculate' leaving the calculation of the AVERAGE to move forward.

• Hide or show rows in the table with AppleScript?

  I have a large table number, and I sometimes want to display the entire table and sometimes select a group of lines to hide or show, to make the display of data more convenient.

  By selecting many rows to hide is tedious (there are many, and they are not contiguous).  So I would use AppleScript to do this.  But in the numbers AppleScript dictionary, I don't see any way to apply an attribute "hidden" in rows, columns or beaches.  Y at - it a trick I'm missing?  Or it simply not exist in the current implementation?

  Thank you

  AFAIK, you can't hide a line or set a height of 0 using AppleScript, although I suggested that any time via numbers of > provide comments numbers in the menu.

  What you could do is filter the table to hide the lines, probably by adding a column filter designating the lines that you want to see (or, conversely, hide).  This filter can be turned on and off via AppleScript using the filtered table property, although it would probably be easier to do via the integrated interface.

• Digital limit - several tables and 1 table limit test

  Hello!

  I am quite new to Teststand and I'm stuck with a problem whose solution should not be otherwise complex... (I think...).

  I would use a "limit test digital"vi (LabVIEW module). " This vi returns 3 paintings and I would define 1 "min/max" for each table.

  that is to say:

  Array1 => each element compared to min - 1 & max1

  Array2 => each element compared to min2 & max2

  ARRAY3 => each element compared to min3 & max3

  For 1 table, I found this solution: I write Locals.ARRAY1 [RunState.LoopIndex] 'DataSource' and all the elements of the array are compared to the limits that I chose. Of course, when I add 2 tables, the same limits are compared to these new windows but I would allocate 1 limits given in table 1.

  Does anyone have an idea of an easy solution?

  My code Teststand and the small vi are here below if this might help.

  Thank you in advance!

  Consider this example.  The trick is to repeat a measurement on the Data Source tab.

• multi line / rowspan header table

  I need a table with a head composed of multiple rows and columns.

  Is this possible with CVI and if so, how?

  Column headers or a table row can be multiline like (almost) any other item of text in CVI signs: you can get part by pressing Ctrl + enter if you change the text in the editor of the IUR. You need to increase the size of header to fitthe newlabel line.

  However, unfortunately it is not possible to have more than one header line in the native tables of CVI. In addition, it is not possible to merge cells on some lines as you can do in Excel, so when I need a setting more complicated for the headers I normally use a separate to table it. The table "header" is defined as an indicator, and I put the cell widths according to my needs.

  You can see the two tricks in this example:

  

• Disable "insert the front element / remove item ' in the table

  Hello guys.

  It is possible to deacitvate function "insert the front element / delete" appears after right-clicking on a table in the front?

  "Description and trick" should stay.

  Thank you.

  Alex

  You can customize the context menu to remove elements of the request and keep others:

  Click on the table (and not on the array element!) in the Panel and select Advanced-> Menu contextual Run - Time-> Edit...

  This brings the context Menu Editor:

  Change the control drop-down menu of "Default" to "Custom".

  Select it "?" line in the tree on the left control.

  on the right, change the element Type of the "user position" «Application point-> Description and Tip...» »

  It automatically fills the corrent name and the tag.

  Save the rtm either in a file or in the control.

  LV will automatically manage elements of the application in the control, any necessary events.

  I sometimes find the function "Menu copies" of the context menu very useful if I want to just disable some elements.

• compare two tables

  I have two paintings like these

  Table 1 table 2

  a 1

  a      5                                 a

  b      2                                 b

  c      3                                 f

  d      4                                 g

  e      5                                 h

  f 6

  g 7

  g 10

  h 8

  h 9.

  with what I have now, I can create a table that lists the matching elements

  Results:

  a          1

  b          2

  f           6

  g          7

  h          8

  However, it does not save the two sets of a, g, h, only the first instance. Someone knows how to fix this?

  Any help is appreciated

  A loop inside another loop FOR FOR should do the trick.  Have the index of auto outer loop on the parameters of search and index of auto inner loop on the search table.  On a match, add this element to the list.

  

• Store the new values in the table in the new row so that the 'old' remains in the previous lines

  Hello

  I am a student of genius embedded. I did a VI where I change the values of digital controls, and it saves it as a table.
  I want to store the pair of new values in the new row of this table.
  I have attached a VI where I can change the values of numeric control, as well as the number of lines from another control. But when I change the values, all values in the output table change including values in the previous row. I want these lines to be unchanged and that new line to update.

  Need help.

  If I understand correctly, you want to always 4 models. If so a 2D table will do the trick (see annex VI), otherwise crossrulz' solution should work.

• Host to the target tables

  I'm trying to transfer a picture of the LabVIEW host program to the target in real time on a cRIO.

  I'll set up a controlled loop that transfer values one via shared Variables.

  It works fine when I run running to highlight.

  However, if I have both allow to run at full speed, something goes wrong

  and the size of the array ends correctly on the target.

  Is there some tricks on how to transfer tables down

  host to the target, or all the other pitfalls I should be aware when

  work on a real-time target?

  And Yes, I never took the course of the RT, so there might be some vital info miss me.

  Hi Martin,

  Why don't you use a SharedVariable taking a picture? Why can you transfer data one by one?

• Permutation between 2 lines in a control table

  How do swap you 2 lines in a table without delay effect?

  Currently, I copied all the data for a row to a temporary buffer, crush the line with the line to be traded. Then replace the line interchanged with the data in the temporary buffer, something like the bubble sort algorithm.

  I've only used the "GetTableCellVal" and "SetTableCellVal" functions with multiple loops "for".

  I'm able to exchange between the rows, but the Exchange takes some time.

  No idea how to switch lines without delay a time important?

  If all the cells in each row have the same type of cell (and the type of data, if they are digital) then you can use GetTableCellRangeVals / SetTableCellRangeVals instead, which should speed things up.

  Another trick is to hide the table temporarily (attribute ATTR_VISIBLE) around the entire operation. This prevents the SetTableCellVal or SetTableCellRangeVals to start a new drawing of the table. Redesigns can be slow, and in this case you don't need any drawing until you have finished with the swap. When you make the table visible once again, it will redraw automatically the next time that the events are handled.

  An alternative to creating and getting each value is to use the Clipboard table functions. I don't really know if it would be faster, but you can test it and find out. The code should look like this:

  GetNumTableRows (Panel, PANEL_TABLE, & numRows);
  InsertTableRows (Panel, PANEL_TABLE, numRows + 1, 1, VAL_USE_MASTER_CELL_TYPE);
  ClipboardPutTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE (row1));
  ClipboardGetTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE(numRows+1), NULL);
  ClipboardPutTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE (row2));
  ClipboardGetTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE (row1), NULL);
  ClipboardPutTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE(numRows+1));
  ClipboardGetTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE (row2), NULL);
  DeleteTableRows (Panel, PANEL_TABLE, numRows, 1);

  It was not clear from your description that you can assume that the two lines to be swapped are always adjacent. If they are, then the code above could be greatly simplified, since in this case, simply make a copy of leapfrog:

  InsertTableRows (Panel, PANEL_TABLE, topRow + 2, 1, VAL_USE_MASTER_CELL_TYPE);
  ClipboardPutTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE (topRow));
  ClipboardGetTableVals (Panel, PANEL_TABLE, VAL_TABLE_ROW_RANGE(topRow+2), NULL);
  DeleteTableRows (Panel, PANEL_TABLE, topRow, 1);

  Hope this helps,

• Reduce the number of cells displayed by indicator table

  When I'm hacking through a few screws I inherited, I often create a table indicator to track data.  I have an oversized indicator, i.e. perhaps seven cells for what turns out to be a five-element array.

  I can easily increase the number of cells is displayed but seem not to be able to reduce their.

  Y at - it a trick I'm missing?

  When you first place a 1 d table control or an indicator, LabVIEW is unclear if you can stretch it horizontally or vertically.

  The RESIZE tool, that you get so something on the lower right.

  

  Once you have decided that you want to extend vertically, if you want to resize once again, the point of RESIZING is at the bottom of the Center.

  

  If you have it stretched horizontally and want to resize again, the point of RESIZING is the center of the right side.

  

  Is - this good user interface?   No, if you ask me.  But nobody asked me.  It's the way it is, however.

• Interleaving of tables

  Hello

  I have 4 tables of doubles.

  The tables of each have the same number of elements.

  I want to combine them into a single table, so that the elements for the original paintings are intertwined.

  I.E.

  a[0] , a[1] , a[2] ..............

  b[0] , b[1] , b[2] ..............

  c[0] , c[1] , c[2] ..............

  d[0] , d[1] , d[2] ..............

  Becomes,

  a [0], b [0], c [0], d [0], [1], b [1]...

  I can write a function, but I recall it being a library function to do this.

  However, I don't remember what we call the library feature, and I'm not.

  It is my memory playing tricks, or can someone point me to it?

  Ah!

  I just found it.

• Invert the table to the Add element to the front of the performance of Bay

  Hi all

  I read in a few places that reverse an array to add the element to the front of it will give the best performance since no new allocation of memory is necessary.

  I have 2 questions about this process:

  1. "reverse a table on requires pointers change.»

  Is that mean that a table in Labview is like a linked list? who has pointers that point to the next element.

  So when this inverse process occurs, the head of the linked list will be the last element of the array, and all links in the linked list will require a change.

  

  Step 1: table of moose with one extra space at the end

  Step 2: Matrix inverse

  Step 3: Add a new item at the end of the table opposite

  Step 4: Reverse again.

  2. the exercise of reverse Add then reverse is even worse in fact. Why is this?

  

  

  "Overhead" is the need for new buffer allocations, which indireclly affects runtime but also memory.

  Yes, often the paintings have an additional memory beyond the end of the table to avoid the resizing with each adding an item...

  Your FAQ quotes says nothing about any reversal trick. To do this, the elements of the array need reverse look up, then inserted using the space soft (if it exists!), then the need even to reverse ber alements in place. Seems like a lot of work to do over and over again. Yes, it might be slightly more efficient that have to be allocated to each prefix operation but we do not really know what the compiler does. Maybe if soft is available, it would be to move all the items up and insert the element first, make a new allowance that occasionally necessary. Who knows? I have the greatest respect for Darren, the author of the "source". Perhaps he can clarify what he writes.

  Benchmarking valid what is quite difficult.

  In all cases, you often know the final size, so it can be distributed in one shot and the items replaced with valid data that you will. It's always orders if magnutide more effective than any other solution.  If you need to grow an element of a table at a time, add at the end, never at the begginning.
